An algebra for creating and querying multimedia presentations

Over the last few years, there has been a tremendous increase in the number of interactive multimedia presentations prepared by different individuals and organizations. In this paper, we present an algebra for creating and querying interactive multimedia presentation databases. This algebra operates on trees whose branches reflect different possible playouts of a set of presentations. The algebra not only extends all the classical relational operators to such databases, but also introduces a variety of novel operators for combining multiple presentations. As our algebra supports merging parts or all of existing presentations, this algebra can also be used as an authoring tool for creating multimedia presentations. We prove a host of equivalence results for queries in this algebra, which may be used to build query optimizers for interactive presentation databases.     

Dynamic playout scheduling algorithms for continuous multimedia streams

In this paper, we investigate a playout scheduling framework for supporting the continuous and synchronized presentations of multimedia streams in a distributed multimedia presentation system. We assume a situation in which the server and network transmissions provide sufficient support for the delivery of media objects. In this context, major issues regarding the enforcement of the smooth presentation of multimedia streams at client sites must be addressed to deal with rate variance of stream presentations and delay variance of networks. We develop various playout-scheduling algorithms that are adaptable to quality-of-service parameters. The proposed algorithms permit the local adjustment of unsynchronized presentations by gradually accelerating or retarding presentation components, rather than abruptly skipping or pausing the presentation materials. A comprehensive experimental analysis of the proposed algorithms demonstrates that our algorithms can effectively avoid playout gaps (or hiccups) in the presentations. This scheduling framework can be readily used to support customized multimedia presentations.     

Limits of PowerPoint’s Power: Enhancing students’ self-efficacy and attitudes but not their behavior

The effects of accompanying lectures with computer-mediated PowerPoint presentations or PowerPoint generated overheads on students’ self-efficacy, attitudes, course performance, and class-related behaviors were examined. Two Introduction to Developmental Psychology sections were initially taught with lectures accompanied by either overheads or computer-mediated presentations. The teaching format was switched halfway through the semester. Students reported higher self-efficacy and more positive attitudes toward the class with computer-mediated presentations. They also claimed that the website was more interesting and useful under these teaching conditions, indicating a halo effect of the computer-mediated presentations. However, the teaching format did not appear to affect course-related behavior, such as performance on exams, class attendance, participation in class discussions, or course website usage.     

Delivering presentations from multimedia servers

Most multimedia servers reported in the literature are designed to serve multiple and independent video/audio streams. We think that, in future, multimedia servers will also serve complete presentations. Multimedia presentations provide unique opportunities to develop algorithms for buffer management and admission control, as execution-time consumption requirements of presentations are known a priori. In this paper, we examine presentations in three different domains (heavyweight, middleweight, and lightweight) and provide buffer management and admission control algorithms for the three domains. We propose two improvements (flattening and dynamic-adjustments) on the schedules created for the heavyweight presentations. Results from a simulation environment are presented.

TAO: Temporal Algebraic Operators for modeling multimedia presentations

This paper presents TAO: a language based on Temporal Algebraic Operators for composing complex multimedia presentations. Unlike traditional approaches used to specify multimedia presentations, TAO relies on a well-defined semantics with an underlying temporal model based on intervals and causal relations between time points. We derive some properties of TAO presentations and show how to execute TAO presentations on an execution engine: a TAO presentation is compiled into a set of instructions interpreted by the execution engine.     

Scheduling multimedia presentations in educational digital libraries

An educational digital library is a specialized digital library containing instructional materials, such as class lectures, seminar presentations, and various training materials. These materials consist of a combination of audio, video, and image data. In such an environment, basic parts of multimedia data are usually stored in databases and sophisticated multimedia presentations may be assembled to generate various presentations. In this paper, we investigate a theory of the scheduling strategies for supporting the synchronized presentations of multimedia streams which is applicable to educational digital libraries. This scheduling theory includes the specification and representation of synchronization on media streams, the realization of appropriate synchronization granularity, and the scheduling principles for the presentations of multimedia streams. This investigation formulates criteria for specifying and scheduling the skipping/pausing of media streams with asynchronous presentations when various delays occur. Adaptability to various quality-of-service requirements is supported in the scheduling strategies. Various synchronization mechanisms at both client and server sides are proposed to implement the scheduling theory. Experimental analysis is conducted using instructional materials.

Adaptive Multimedia Presentation Strategies

Multimedia presentations comprise various media objects such as text, audio, image, and video that are delivered to users according to certain temporal relationships. In stored multimedia presentations, these temporal relationships are explicitly formulated by the author(s) and stored along with the presentations. However, it is difficult to ensure that these temporal relationships are always strictly preserved in real-time, distributed multimedia presentations. This is due to the fact that various components of the run-time environment such as operating system and network may offer only best effort services, i.e., they may not be able to provide any real-time guarantees. In this paper, we survey the different approaches that can be used for adapting multimedia presentations to handle instances where temporal relationships cannot be preserved in a strict manner. We classify these approaches into three categories and discuss when these categories of adaptations can be used.     

A video recording and viewing protocol for student group presentations: Assisting self-assessment through a Wiki environment

The purpose of this research was to firstly develop a protocol for video recording student group oral presentations, for later viewing and self-assessment by student group members. Secondly, evaluations of students' experiences of this process were undertaken to determine if this self-assessment method was a positive experience for them in gaining insights into the quality of their group's presentation. Participants were students undertaking a first year course in a bachelor of business degree within an Australian university. Students were surveyed twice, once prior to group formation to determine their previous oral group presentation experiences and then after viewing their presentations. Data from survey items assessing students' perspectives on the utility of viewing their video presentations, within their group Wikis, revealed that watching the video of their group presentation was an effective method of feedback and could improve both group and individual performance in the future. Further, content analysis of open ended survey questions and focus groups identified that students were highly engaged in the activity and after reviewing and reflecting on their video recording had deeper insights and raised awarenesses of making group presentations. Students identified that this experience would benefit any future group oral presentations they made.
